APPARATUS FOR EXCHANGE HEAT.

Application filed'september 13, 1926. Seriallio. 134,964.

My invention is adapted for inclusion in a house heating system wherein -a gas consuming' heater unit is connected by pipes with a distant radiating unit or units for heating respective rooms or any. inclosure in which such a radiator may be located; both heating and radiating units being preferably of what is known as honeycomb or sinnlar cellular construction, and said system including means for maintaining a forced clrculatiorr of both water within the heating system and the air heated by the radiator; such circulations being respectively effected by a pump and fans; both preferably operated by electric motors, with thermostatically operative controlling means.

My 7 copending application Serial No. 189,090 filed May 5, 1927, includes claims for the water-heaterv herein contemplated, and myco ending ap )lication Serial No. 189,091 filed lllay 5, 192 includes claims for the heat distributing apparatus herein contemplated; both of said applications being divisions of this applicatiomwherein the claims are restricted to specific features of construction and arrangement of radiating devices and. their appurtenances.

My .'nvention includes the various novel Said radiator structure is provided with the fan 14 and the motor 15; the latter being preferably mounted within the circular inner casing 16 of the radiator structure in concentric relation with said casing6, and within asoft rubber band 17 which minimizes the transmission of vibrations from the fan and the motor. Said casing 6 is, preferably detachably, rigidly connected with the face plate" 18 which is, preferably detachably, rigidly connected with the. outer casing 19 which is adapted to fit in a recess 20 of a ceiling 21, but maybe set in any wall substantially flush therewith.

The zone 23 of said face plate 18 is perforated or otherwise made foraminou's so as toadmit air to the inner side of the radiator structure through the space between the latter and said outer casin 19; which air is driven outwardly b the rotation of said fan 14 throughthe tu es 2, wherein the air absorbs heat from the hot Water or other heating fluid in the passageways 5.

The construction and arrangement of the radiator and its appurtenances above described are such that they may be readily installed; the pipes12 and 13 being con.- veniently formed of soft copper tubing and features of construction and arrangements the couplings 11 being conveniently of what hereinafter more definitely specified.

In said drawings; Fig. I is a fragmentary front elevation of a radiator unit as mounted in a ceiling or other wall.

. Fig. II is a sectional view of said radiator.

unit, partly in eleyation.

In said figures; the radiator cellular'struc1 ture 1 includes a congeries of primarily c lindrical flue tubes 2, referably-made of t inv sheet copper, and ii site. ends 3 ex anded to hexa onal form so as'to fit tight y to ether wit their intermediate cylindrica portions in pro r spaced-relation to afford passageways 5. e-

' tween them for hot water or-steam. Said flue tubes 2. are assembled within the cylindrical circumferential casing 6 conveniently with circular series of six filling ieces 8 at each of the arially oppositeen s thereof. Said radiator structure is provided with opposite side conduits 9 and 10. Said condiiits arerespectively provided with couplin s 11, adapted for detachable connection wit the respectivepipes 12' and 13 through which the heating fluid is circulated in the passageways 5, in 50111190171011 with the heaterof the system above contemplated.

aving their oppoattaine of steam; with the advantage that a reater eflieienfy per until of apparatus is t ereby as compared with apparatus in which the water is' continually maintained below itsboilin oint.

. Moreover, I n it convenient to provide a thermostatic device 25 arranged'to control the operation of said motor 15, in accordance with the temperature of the air circulated by said fan 14; which device may be athermostatically operative electric switch included in the circuit of said motor but more or less remote from the latter.

Although I prefer to effect forced-circulation of the. air with respect to the heatmg surfaces of the radiators aforesaid, by

' means of electrically actuated fans; other said casing and radiator and through the' means forefi'ecting such circulation may be & employed and, in fact, such circulating means may be omitted and the air circulated by convection.

Therefore, I do not desire to limit myself to the precise. details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of my invention, as defined in the appended claims.

I claim:

1. In a heatin'gsystem, a radiator of cellular structure, formed of thin sheet metal walls,forming passageways for air; of a casing exterior to said radiator, in spaced relation therewith; and means arranged to effect the forced circulation of air between latter. t V,

2. In a heating system, a radiator of cellular structure, formed of thin sheet metal walls, forming passageways for air; of a casing exterior to said radiator, in spaced relationtherewith; and means arranged to efiect the forced circulation of air between saidv casing and radiator in one direction, and through the radiator in the opposite direction. I

3. A heating system, as described in claim 1 2; wherein the circulating means is an electric motor; and a thermostat arranged to' control the operation of said motor.

4. In a heating system, the combination with a radiator of cellular structure, formed of thin sheet metal walls, arranged as passageways for air; of a casing for said radiator, having an annular wall in spaced relation with said radiator, and a face late having a foraminous area between said radiator and casing; said face plate bein arranged to extend substantially flush with a building wall, in which said casing extends.

5. In a heating system, as described in claim 4; means arranged to circulate air inwardly through said foraminous areaand outwardly through said radiator, including a .in said casing, behind said radiator.

6.'In a heating system, as described in claim 4; means arranged to circulate air.
